Introduction


European regulators are tightening crypto tax reporting through the EU’s DAC8 framework, aligning with the OECD’s Crypto Asset Reporting Framework (CARF) and focusing enforcement on identifiable intermediaries like exchanges and custodians. For now, decentralized finance (DeFi) largely sits outside these reporting rules because protocols often lack a clear reporting entity, but that exclusion is fragile as authorities explore AML-style accountability and whether certain DeFi fronts can be treated as virtual asset service providers (VASPs).


Institutional-facing development continues to pull DeFi closer to traditional compliance expectations, highlighted by Bitcoin DeFi initiatives aimed at corporate treasury use. A partnership between Animoca Brands Japan and RootstockLabs underscores growing Japanese institutional interest in using Bitcoin beyond custody—expanding into onchain tools for treasury management, liquidity, and financial operations on networks secured by Bitcoin’s proof-of-work.


In the United States, lawmakers are revisiting crypto market structure with proposed changes to the Digital Commodity Intermediaries Act (DCIA), keeping DeFi as a central point of contention as policymakers weigh the boundaries of CFTC vs SEC oversight. Meanwhile, adjacent sectors are maturing: DePIN is described as a roughly $10 billion category generating meaningful onchain revenue despite token drawdowns, and Citrea’s zk-rollup launch renews the Bitcoin block space debate by turning BTC into active collateral for lending, stablecoins, and structured products—while broader DeFi markets remain pressured in weekly performance data.


Background


The regulatory landscape for digital assets is evolving at an unprecedented pace, yet decentralized finance (DeFi) continues to operate largely outside the reach of traditional regulatory frameworks. While authorities worldwide are implementing comprehensive crypto tax reporting regimes and tightening oversight of centralized exchanges and custodians, the decentralized nature of DeFi protocols presents a unique challenge that has, for now, left this sector in a regulatory gray zone.


The European Union's DAC8: A Case Study in Selective Enforcement

The European Union's new crypto tax reporting regime, known as the Directive on Administrative Cooperation 8 (DAC8), came into effect on January 1, 2026, marking a significant milestone in crypto compliance. However, its scope reveals an intentional and strategic choice by regulators: focus enforcement efforts on identifiable intermediaries rather than attempting to regulate decentralized protocols directly.


According to Colby Mangels, global head of government solutions at TaxBit, this approach prioritizes "enforceable targets" over comprehensive coverage. The regulation leverages the OECD's Crypto Asset Reporting Framework (CARF), which establishes international standards for automatic exchange of crypto tax information. Both DAC8 and CARF mandate that Reporting Crypto-Asset Service Providers (RCASPs)—including centralized exchanges, custodial wallet providers, brokers, and payment service providers—collect detailed user information and transaction data for tax authorities.


The information reporting requirements are extensive. RCASPs must gather personal identification data including full legal names, residential addresses, Tax Identification Numbers (TINs), dates of birth, and countries of tax residence. On the transactional side, platforms must report the type, date, time, quantity, and EUR value of each transaction, along with applicable fees and wallet addresses involved. This level of granular reporting creates unprecedented tax transparency for centralized crypto activities.


Yet DeFi platforms—including decentralized exchanges (DEXs) like Uniswap or PancakeSwap, lending protocols such as Aave and Compound, and staking mechanisms operated through individual validator nodes—remain largely outside this reporting mandate. The reason is straightforward: these protocols function as smart contracts without identifiable intermediaries who can be compelled to report. They typically only interact with wallet addresses, not the tax identities of users.


Understanding the Regulatory Rationale


The decision to exclude DeFi from frameworks like DAC8 isn't an oversight—it's a pragmatic acknowledgment of enforcement limitations. Traditional financial regulation operates on a foundation of institutional accountability. Banks, brokers, and exchanges are legal entities with physical offices, identifiable management, and jurisdictional ties. They can be licensed, audited, sanctioned, and if necessary, shut down.


Decentralized finance fundamentally disrupts this model. DeFi protocols are typically governed by immutable smart contracts deployed on public blockchains. Once launched, many operate autonomously without ongoing intervention from their creators. Some are governed by Decentralized Autonomous Organizations (DAOs), where decision-making is distributed among token holders rather than concentrated in a corporate hierarchy. This architectural design makes traditional regulatory enforcement extraordinarily challenging.


Consider a practical example: if a centralized exchange like Coinbase fails to implement adequate Anti-Money Laundering (AML) controls, regulators can impose fines, revoke licenses, or pursue criminal charges against executives. But who do you hold accountable when a DeFi protocol facilitates illicit transactions? The original developers may have relinquished control. The smart contract operates autonomously. The DAO members may be pseudonymous and globally distributed. Traditional enforcement mechanisms struggle to find purchase in this environment.


The OECD's Global Framework and International Coordination


The OECD's Crypto Asset Reporting Framework represents a broader international effort to standardize crypto tax compliance across jurisdictions. Finalized in June 2023, CARF extends the principles of the Common Reporting Standard (CRS)—which governs automatic information exchange for traditional financial products—to the digital asset space.


As of December 2025, 76 jurisdictions have committed to implementing CARF, with 48 targeting exchanges by 2027, 27 by 2028, and the United States by 2029. This global coordination aims to prevent regulatory arbitrage, where crypto businesses might relocate to jurisdictions with lax oversight.


CARF's definition of "Crypto-Assets" is deliberately broad, encompassing "a digital representation of value that relies on a cryptographically secured distributed ledger or similar technology to validate and secure transactions." This includes cryptocurrencies, ERC-20 tokens, tradeable NFTs, and stablecoins. However, it excludes Central Bank Digital Currencies (CBDCs) and certain electronic money products, which fall under the amended CRS.


The framework identifies three reportable transaction types: exchanges between crypto-assets and fiat currency, exchanges between different crypto-assets, and transfers of crypto-assets (including using crypto for purchases or transfers to unhosted wallets). Retail payment transactions exceeding $50,000 also trigger reporting obligations.


Like DAC8, CARF's enforcement mechanism relies on RCASPs. The framework's extraterritorial implications mean that platforms serving users in committed jurisdictions must comply regardless of where the platform is headquartered. This has already prompted some non-compliant offshore exchanges to block users from participating jurisdictions rather than implement costly compliance infrastructure.


Why DeFi Presents Unique Regulatory Challenges


The challenges of regulating DeFi extend beyond simple enforcement difficulties. Several structural characteristics create friction with traditional regulatory frameworks:


The Classification Dilemma


Financial regulation typically categorizes activities into distinct buckets: securities trading, banking, derivatives, payment processing, each with specialized rules. DeFi protocols often blur these boundaries. A single platform might simultaneously facilitate token swaps (exchange activity), provide yield farming opportunities (investment products), offer lending and borrowing (banking services), and enable synthetic asset exposure (derivatives). Which regulatory framework applies? The answer is often unclear, creating legal uncertainty for both projects and users.


The Immutability Challenge


Smart contracts, once deployed on most blockchains, are immutable—they cannot be altered or updated. This creates a fundamental tension with regulatory compliance. Financial regulations evolve; new AML requirements emerge, tax reporting obligations change, and sanctions lists update regularly. Traditional financial institutions adapt their systems and procedures accordingly. But DeFi protocols frozen in code cannot automatically respond to regulatory changes without built-in upgrade mechanisms.


Some projects address this through upgradeable smart contract architectures with governance-controlled modification capabilities. However, this introduces centralization—the very characteristic DeFi seeks to minimize—and creates new vulnerabilities if governance is compromised.


Cross-Border Complexity


DeFi protocols operate globally by design. A user in Germany can interact with a protocol governed by a DAO with token holders in twenty countries, deployed on a blockchain with validators distributed across six continents. Which jurisdiction's laws apply? Where can enforcement action be brought? Traditional notions of territorial jurisdiction struggle to accommodate this reality.


International coordination efforts like CARF help, but complete harmonization remains distant. Regulatory divergence between jurisdictions creates compliance complexity and opportunities for regulatory arbitrage.


AML and KYC Implementation


Anti-Money Laundering and Know Your Customer requirements form the backbone of financial crime prevention in traditional finance. Banks and exchanges verify customer identities, monitor transactions for suspicious patterns, and report potential money laundering to authorities.


DeFi's permissionless nature conflicts with these requirements. Users interact with protocols through wallet addresses without providing personal information. While blockchain transactions are transparent and traceable, connecting wallet addresses to real-world identities requires additional investigative work.


Some DeFi projects are implementing "decentralized identity" solutions using Zero-Knowledge Proofs (ZKPs), which allow identity verification without exposing personal information. Others partner with third-party KYC providers for certain protocol features. However, these solutions add friction and complexity, potentially undermining the user experience advantages that drive DeFi adoption.


The U.S. Treasury's proposed GENIUS Act illustrates the regulatory push in this direction. Signed into law in July 2025, it establishes frameworks for stablecoin issuers and proposes embedding KYC mechanisms directly into DeFi smart contracts. This "compliance-by-design" approach attempts to encode regulatory requirements into protocol architecture, though implementation challenges remain significant.


The Illicit Finance Concern


Regulators' caution toward DeFi isn't purely theoretical. The sector's pseudonymous nature and limited oversight have made it attractive for illicit financial activities. The U.S. Treasury's 2023 DeFi Illicit Finance Risk Assessment highlighted that DeFi services accounted for a significant portion of stolen virtual assets, with cybercriminals—including state-sponsored actors from North Korea—exploiting DeFi protocols for money laundering.


Privacy-enhancing protocols like Tornado Cash, which obfuscate transaction histories, have drawn particular regulatory scrutiny. The U.S. Office of Foreign Assets Control (OFAC) sanctioned Tornado Cash in August 2022, marking an unprecedented attempt to restrict interaction with a decentralized protocol. This action sparked debate about whether code itself can be sanctioned and raised questions about the boundaries of regulatory authority in decentralized systems.


The Financial Action Task Force (FATF), which sets global AML standards, continues to emphasize that Virtual Asset Service Providers (VASPs)—a category that includes many DeFi platforms—should face the same AML obligations as traditional financial institutions. FATF's 2025 Virtual Assets update reiterated this position while acknowledging the practical difficulties of applying AML frameworks to genuinely decentralized infrastructure.


A Shifting Regulatory Landscape: 2025 and Beyond


Despite current exemptions, the regulatory environment for DeFi is evolving rapidly. Multiple jurisdictions are developing frameworks that may eventually bring DeFi within regulatory scope:


United States


The U.S. regulatory approach has been characterized by enforcement actions rather than clear rulemaking, creating uncertainty for DeFi projects. However, 2025 has seen movement toward clarity:


  • The CLARITY Act, enacted in August 2025, delineates jurisdictional boundaries between the CFTC (digital commodities) and SEC (securities-like tokens).


  • The Digital Asset Market CLARITY Act (passed July 2025) institutes dual SEC/CFTC registration with provisional compliance periods.


  • The GENIUS Act establishes stablecoin frameworks with 100% reserve backing requirements and regular audits.


  • The SEC's formation of a dedicated Crypto Task Force and its decision to drop enforcement against Coinbase signal a shift toward cooperative engagement.


Notably, the Department of Justice issued guidance titled "Ending Regulation by Prosecution," instructing prosecutors not to charge regulatory violations where developers lack custody and control over user assets—a significant protection for genuinely decentralized projects.


European Union


Beyond DAC8, the EU has implemented several frameworks affecting the crypto ecosystem:


  • Markets in Crypto-Assets Regulation (MiCA), which became fully operational in late 2024, establishes comprehensive rules for centralized crypto activities while explicitly excluding fully decentralized protocols.


  • MiCA 2.0 discussions are underway, expected to address DeFi directly with potential provisions for DAO identity, protocol audits, and user risk disclosures.


  • The Digital Operational Resilience Act (DORA) requires DeFi projects using third-party infrastructure to demonstrate ICT disruption management capabilities.


Asia-Pacific


Singapore and Hong Kong are leading Asian regulatory development through sandbox approaches. Singapore's Major Payment Institution (MPI) licensing framework and Hong Kong's exploration of DAO recognition models represent pragmatic efforts to accommodate decentralization while maintaining oversight.


Japan, with growing institutional interest in Bitcoin treasury management, is working with blockchain infrastructure providers like RootstockLabs to deliver Bitcoin-native DeFi tools for corporate treasury applications—an example of DeFi gradually integrating with traditional finance under regulatory frameworks designed for institutional participants.


The Future: Will DeFi Regulation Remain Elusive?


The current exemption of DeFi from tax reporting and other regulatory frameworks should not be interpreted as permanent. Regulators are increasingly viewing this as a transitional state rather than an enduring reality. Several factors suggest tighter DeFi oversight is inevitable:


Regulatory Technology Evolution: As blockchain analytics capabilities advance, the practical barriers to monitoring DeFi activity are decreasing. On-chain analytics firms can track fund flows, identify patterns consistent with money laundering, and in some cases, connect wallet addresses to real-world identities. The Bank for International Settlements has proposed "Embedded Supervision," where regulatory compliance is automatically monitored by reading blockchain ledgers.


Institutional Participation: As traditional financial institutions explore DeFi for efficiency gains and new revenue streams, they bring their regulatory obligations with them. Banks and asset managers operating in DeFi must comply with existing financial regulations, creating pressure for clearer DeFi-specific frameworks.


Market Maturation: The DeFi sector is professionalizing. Early resistance to any form of regulation is giving way to recognition that regulatory clarity—even if burdensome—provides legitimacy and enables sustainable growth. Forward-thinking DeFi projects are proactively implementing compliance features, viewing them as competitive advantages rather than obstacles.


Political Will: The 2025 regulatory developments demonstrate that political and regulatory appetite for crypto oversight is intensifying rather than diminishing. The combination of consumer protection concerns, financial crime risks, and tax collection imperatives creates strong incentives for authorities to extend their reach to DeFi.


Navigating the Compliance Landscape


For DeFi protocols and projects, the current regulatory environment presents both opportunities and risks:


Proactive Compliance as Competitive Advantage: Projects that implement robust compliance frameworks early can differentiate themselves in an increasingly crowded market. Access to institutional capital often requires demonstrating regulatory alignment, making compliance a business enabler rather than merely a cost center.


Governance Structures Matter: How a project is governed significantly impacts its regulatory exposure. Genuinely decentralized protocols with distributed governance face different regulatory treatment than projects where founders retain effective control. DAOs should structure their governance to align with compliance obligations while preserving decentralization principles.


Geographic Considerations: While DeFi operates globally, strategic decisions about entity structure, team location, and primary markets can significantly influence regulatory risk. Projects should carefully consider where to establish legal entities and which users to serve.


Technology Solutions: Innovations like Zero-Knowledge Proofs, decentralized identity protocols, and on-chain compliance tools offer paths to meet regulatory requirements without sacrificing the core value propositions of DeFi. Investment in these technologies may prove crucial for long-term viability.


Conclusion


The deliberate exclusion of decentralized finance from emerging crypto regulatory frameworks like the EU's DAC8 and the OECD's CARF highlights a fundamental tension in the evolution of digital finance. Regulators recognize the enforcement challenges posed by genuinely decentralized protocols and have chosen to focus resources on identifiable intermediaries where traditional oversight mechanisms can be effectively applied.


However, this exemption exists in a dynamic rather than static environment. As DeFi's total value locked grows, as institutional participation increases, and as regulatory technology capabilities advance, the pressure to bring DeFi within regulatory scope will intensify. The illicit finance risks associated with unregulated DeFi activity create additional imperatives for authorities to develop effective oversight mechanisms.


The future of DeFi regulation likely lies not in direct application of traditional financial frameworks to decentralized protocols, but in innovative approaches that accommodate decentralization while addressing legitimate regulatory concerns. Embedded supervision, compliance-by-design smart contracts, decentralized identity solutions, and risk-based regulatory frameworks tailored to DeFi's unique characteristics represent potential paths forward.
